Y k1 aZZ @whom if may@ concern Be it known that GEORGE F. Ho'rc INS, a citizen of the Ugxited States, residing at Worcester. in the county of Wioreester and State of Massachusetts, have invented certain new and useful Improvements in Looms for Weaving Tufted Fabrics, of which the following is a s eoificetion.

My invention relates t looms for Weaving tufted 'fabrics of the type sllo'wn and (tesori-ed in U. 5:. Letters Patent, No. 490.23?. in nth tmf., :vein @a1-fiers; or spools tire uso which carry the tutt yarn ivoim-l there() nul the spool trames moving :ire Jurrie-tl by' g i mechaered. to eem-v the tutt yarn f was; bviwxi Werp threads, to cause 'nyuricviling fvozniim tube? to be inseriert vrt-vr. tire .vnzbs. uml then miseri out of.' iinimiefic. mil tl a tutti yarns out oit" to maize the @lo on the ,febr-ie., in the usuel and v...l known vrny. in this class of looms it is nenti-fluff to have :i frictiam de vice lo hold'l the woei. tuning the tutt yarn tti-reitsh ,"fmn rol.,

enel 'the bet-Ween the warp threads, and then returns the spool and spoot frame having the tuft yam tubes thereon to their normal position in the endless chain, so that the rotation of the spool, when the tuft yarn tubes are withdrawn from the fabric, after the tuft yarns have been inserted therein, will not be greater than the rotation required for the length of tuft yarn to be inserted into the fabric and eut oil to form the pile.

ln my improvements in friction device for 'the mit gern spools, whit-,lf moois are nfflin-=erily provided with metal .ends 'or ls, l' pg'micle e. flexible device or plate, ettzmiml to the spool frame and looate at the ou enti of eileli spool, and having u friuli-f urieffe thereon to bear against the outer .eide of the heml of the spool, preferably :it each entithereof. in the direction of the length of the spool. to hold said spool :fggainet rotation.

My friction dei'i is preferably of eirzular si' (lis-k shape et its engaging emi. uml preferably of the Same size as the head, ol the spool, so that the. engaging part of the grip arm of the grip mechanism will bear egizi si'. said friction device. when said grip meolmnism operated to remove a spool mi spool treme 'with the tubes thereon7 from; the endless chain, to .lower their into fi position to vitry the tutt yarn tubes tween the warp threads :intl to mise is m to zvtwn them to the emilees chain. Dmingf im removal of the spool and. spool Trume from the endless chain, :mtl until tlv :ire retiirnetl to their normal posh tion in the mult elmin. the friction on the spool, is. intt'essett ilur'ing :i part. ot' the time. t5 iwi-gte the :iftion of the grip arms of the grip f.. filtran... more firmly against rotation nt this time, es will be readily understood by those skilled in the nrt.

I have only shown in the drawing a detached tutt yam verrier and its holdinq' devine, with my improvements applied there.- to, sutlioient to enable. tlmse skilefl in the lil-t to understand the nature of my invention.
